Abstract
- Terminal oxo and sulfido complexes in the form of (nacnac) V=E(Ntol2) (nacnac = [ArNC(CH3)]2CH−, Ar=2,6-(CHMe2)2C6H3, Ntol2 = −N(C6H4-4-Me), E = O (1), S (2)) were isolated from treatment of the masked three-coordinate vanadium(II) complex, (nacnac)V(Ntol2), with C5H5NO and S8, respectively. Both vanadium(IV) species, 1 and 2, have been characterized by room temperature X-band EPR spectroscopic studies, and in the case of complex 1, a single crystal molecular structure confirmed the presence of a terminal oxo moiety. Moreover, reaction of (nacnac)V(Ntol2) with diphenyl–disulfide and diphenyl–diselenide results in the reductive cleavage of these compounds to produce the vanadium(III) complexes (nacnac)V(XPh)(Ntol2) (X = S, (3), Se (4)). A molecular structure of the phenylsulfide complex, 3, confirmed formation of the d2 complex resulting from reductive cleavage of the S–S bond. [Copyright &y& Elsevier]
